To all 'tolhom ist 'may concern I Beit known that I, GEORGE W. BERNAUER,

a citizen of the United States ofAlmerica,

residing at St. Charles, county v.of St.

Charles, State of Missouri, Ahave invented.

new and useful Improvements in Processes of Drying Solutions Applied to Kird, ALeather, or other Materials, of which the following is a specification. Th`s invention relates fto-processes or methods of drying solutions applied tov leather, kid, calf-skin, or other materials', and-has for itsprime object to afford a process vwhereby so-called;patentleather or "enameling solutions can be applied to a 4`{1 finished shoe and veryquickly dried thereon Without damage tothe sole'and other lparts of said shoe not treated with said sof lasen.

Inthelasting vofshoes made of or comprlsmg patent or enamel leather great trouble has been experienced from. the liability of the brittle finish of such leather to crack and` from the further fact that A...the Saidnishis frequently scratched and other- Wise damaged and' rendered unsightly during the courseof manufacture of the shoe. This necessitates repair before the shoes are merchant-able, which is usuallyT accomplished by sandpapering off the enameled surface of the leather until the defects are. eliminated, applying a coating of collodion, and next applying one or more coats of liquid enamel', each of said coats being allowed to dry thoroughly before another is applied. As one long experienced in the art of shoe manufacture I amaware that, prior to my invention, twenty-four to forty-eight hours were ordinarily required for the hardening of the said coats of enamel before the shoes were in fit condition to pack for shipment,

which, as will be appreciated, entailedthe a finished shoe because the lheat of the 'Wenig-Whether the temperature thereof be i highl or low-Would injuriously aifect Athe sole and other partspf the shoe which were not enameled.

In accordance with the practice ofthe Patent Office in cases of this character, a`-

drawing is filed herewith illustrating an apparatus by aid of Which my process can becarrled out, Figurel being a top plan View' of said apparatus; 2 a .frontelevationfthereof; Fig. 8 a cross-section along line A -B of Fig. Q.; and Fig. 4 a cross-section along line `G-D of Fig. 3. However, I Wish it understood that said process does not depend for its. successful application upon the apparatus shown oranyotherl particular machine. y l,

Referring to the accompanying drawing,

Ain which like numerals refer to likeparts throughout the several views, I-may employ a box-like receptacle l the upper Wall of which is providedwith a plurality of apertures 2 communicating directly With its interior, said apertures conforming in shape to the toe-portion of. a shoe but being slightly less in Width and much less in length than the width and length of the shoe. To fuelsupply pipes 3 are connected burners fl (preferably consisting of a short tube providedwith` an opening 5) an extremity of which is projected within one end of a. combustion chamber G, the same having a plurality of .'apertures?. The opposite eX- tremity of chamber (i is dctachably secured y to a tube 8 which is connected with a4 suction-pipe 9, the latter communicating with the interior of a housing l0 incasing a motordriven -fan (not shown) of any Well-known type. Said housing is prolonged into a tube ll which is coupled with a pipe l2 extend ing, as does tube 8, from end to end of receptacle l and provided with nozzles 13 ,which are arranged in register with each of'apertures 2.'

l Upon the vface of said receptacle are secured Wire arms 14, adapted to lie o n-each side of the upper of a shoe to support the same, While the shoe is further retained in proper position the use of rollers l5 which engage the opposite edges of the sole 15a.

In operation, the 'shoe-toes having been coated with theenameling or other desired Vsolution are supported over and fit Within ra Jertures 2 as best shown in Figs. 3 and-fl,V

ivherebyqhitlu'ill bewnoted that the sole and .other parts ofthesh'fe which are notso coa-' ted and which it is essential to protect from heat are disposed entirely Without receptacle 1. Thereafter, cock 16 being opened the gas supplied by pipes 3 is admitted to burners 4, ignited in combustion-chambers 6 and,

the fan having been started, the flame, toA

gether with a constant current of air admitted through apertures 7, is drawn through tube 8 and the air so heated carried to said fan by Way of pipe 9. From that point said airis blown into tube 11, thence forced along pipe 12 and issuesat high temperature from nozzles 13 Which direct its flow against the solution, but as apertures 2 are of less width and length than the width and length of the finished shoe, it will be appreciated that they 'the usual factory conditions l have demonstrated that but an hour or less is required amaai@ under this process to produce results which have heretofore required many hours.

What Il claim as new and desire to secure by LetterssPatent is 1. The method 'of drying and hardening solutions applied to shoes which comprises the disposition of the part carrying the solution Within a heated receptacle, simultaneously disposing the portions of the shoe not treated With the solution Without said receptacle, and restricting the action of the heat to said part.

2. The method of drying and hardening solutions applied'to shoes which comprises the disposition of the part carrying the sclution Within a heated receptacle, forcing a blast of air against said part, simultaneously disposing the portions of the shoe not treated with the solution without said receptacle,

and restricting the action of the heat and blast to said part.
